Description

The heavily stressed coal petrography stairstepping cylinder of deep-well
Technical field
The present invention relates to a kind of pre- cut coal mining machine roller, especially a kind of adopting suitable for the heavily stressed coal petrography cut of deep-well Coal machine cylinder.
Background technology
Existing coal mining machine roller crushes coal petrography by the rotation cut of the pick-shaped cutter on helical blade and end plate, but In view of the narrow and small exploitation space in actual colliery and severe mining conditions, in the recovery process of the heavily stressed coal petrography of deep-well, Due to the restriction of work space, the size of coal-winning machine can not be too big, and this size for resulting in coal-winning machine cutting motor is restricted, The heavily stressed coal petrography cut needs of deep-well cannot be met.Therefore, need a kind of new energy cut height under certain power situation badly to answer The coal mining machine roller of power coal petrography.
The content of the invention
Technical problem:The purpose of the present invention is to overcome problems of the prior art, proposes a kind of compact conformation, adaptation The heavily stressed coal petrography stairstepping cylinder of deep-well in the narrow and small exploitation space in colliery.
Technical scheme:The heavily stressed coal petrography stairstepping cylinder of deep-well of the present invention, including rear cylinder hub, be connected on rear cylinder hub Placket hub, described rear cylinder hub and placket hub junction are provided with an end plate, and described rear cylinder hub is provided with the spiral shell being connected with end plate In the outer rim of vane piece, helical blade and end plate, interval is furnished with multiple grooves, groove and is respectively fixed with pick and two grooves between Type pick and nozzle, have the pick-shaped cutter for arranging in the shape of a spiral on the placket hub;It is provided with described end plate and is distributed in 120 ° End plate window;The end plate is provided with annular water transport channel, and is communicated with the nozzle water transport channel of annular water transport channel, wheel Hub water transport channel and end plate blade water transport channel.
The rear cylinder hub is consistent with the external diameter of placket hub and equal length.
Described end plate front end face is provided with end plate backplate, is interval with wear rib on end plate backplate.
Beneficial effect:The present invention is rotated on heavily stressed coal petrography by cylinder and opens up stress spron, forms the scope of freedom, real The now exploitation to the heavily stressed coal petrography of deep-well, and being connected by each water channel, ensures the water supply of nozzle to realize the dirt that goes out.Revolve in cylinder During turning, on the placket hub cylindrical envelope diameter formed by pick crown is less than the pick on helical blade on rear cylinder hub The cylindrical envelope diameter formed by crown, in the case of drum driven moment of torsion is constant, on placket hub, pick has higher cut Ability.In heavily stressed coal petrography cutting course, the pick-shaped cutter on placket hub opens one in advance on the heavily stressed coal petrography of deep-well should Coal petrography under power spron, cut is entered in helical blade by end plate window, coal is transported away, in next knife coal petrography cut In, cutting resistance of the pick-shaped cutter above helical blade and end plate in cutting course is substantially less, while on placket hub Pick-shaped cutter is that the cut of next knife separates one stress spron, and the mechanical mining for solving the heavily stressed coal petrography of deep-well is asked Topic, disclosure satisfy that the mining requirement in the heavily stressed coal seam in down-hole, improves the production efficiency and safety condition in the heavily stressed coal seam in down-hole. The present invention by the way of the external diameter such as rear cylinder hub and placket hub, when can effectively transport placket hub pick-shaped cutter cut under cut The coal petrography for coming.And cylinder hub form is simple, easily fabricated.

Specific embodiment
Below in conjunction with the accompanying drawings one embodiment of the present of invention is further described:
As shown in figure 1, the heavily stressed coal petrography stairstepping cylinder of the deep-well of the present invention is mainly by rear cylinder hub 1, placket hub 2, spiral Blade 3, end plate 4, nozzle 5, pick-shaped cutter 6 are constituted.Described rear cylinder hub 1 is connected with placket hub 2, afterwards cylinder hub 1 and placket hub 2 External diameter is consistent, and equal length, by being welded to connect;Described rear cylinder hub 1 and 2 junction of placket hub are provided with an end plate 4;Institute The rear cylinder hub 1 stated be provided with the outer rim of the helical blade 3 being connected with end plate 4, helical blade 3 and end plate 4 interval be furnished with it is multiple Pick-shaped cutter 6 and nozzle 5 are respectively fixed with and between two adjacent grooves in groove, groove;Helical-blade is welded with the helical blade 3 Piece backplate 3-1, wear-resistant block 3-2;The rear cylinder hub 1 is welded with the reinforcement 1-1 of hanger 1-2 and connection helical blade 3 above.
The placket hub 2 welds pick-shaped cutter 6 above;Pick-shaped cutter 6 on the placket hub 2 is arranged in the shape of a spiral, such as Shown in Fig. 1.
Described 4 front end face of end plate is provided with end plate backplate 4-2, be interval with end plate backplate 4-2 wear rib 4-1 and It is provided with end plate in 120 ° of end plate window 4-7 being spaced apart;The end plate 4 is provided with annular water transport channel 4-5, and the company of being provided with Lead to nozzle water transport channel 4-3, wheel hub water transport channel 4-4 and end plate blade water transport channel 4-6 of annular water transport channel 4-5, such as Fig. 3 It is shown.
Operation principle:The present invention cuts the side of one spron in advance using ladder cylinder to the narrow and small exploitation space in colliery Formula, it is possible to increase the ability of the heavily stressed coal petrography of coal-winning machine cut.In roller rotating process, on placket hub, pick crown is formed The cylindrical envelope diameter formed less than the pick crown on helical blade on rear cylinder hub by cylindrical envelope diameter, in rolling In the case of cylinder driving torque is constant, on placket hub, the clipping force of pick-shaped cutter is bigger, therefore in the exploitation of the heavily stressed coal petrography of deep-well When, allow the task that pick-shaped cutter on placket hub 2 undertakes precut to output a spron, the coal cut off is by the end on end plate 4 Disk window 4-7 is transported, and in the cutting of the second knife, the pick on cylinder hub 1 just can hold the heavily stressed coal petrography of spron successfully afterwards Upper light cut, while the pick-shaped cutter on placket hub 2 is the cut of next knife drives a spron.Solve deep-well heavily stressed The mechanical mining problem of coal petrography cut, disclosure satisfy that the mining requirement in the heavily stressed coal seam in down-hole.
Therefore, in heavily stressed coal petrography cut, on placket hub, pick-shaped cutter cut on heavily stressed coal petrography goes out one stress and unloads Carry groove, the coal petrography scope of freedom increases, in the second knife cut after pick-shaped cutter cutting resistance on cylinder hub can be obviously reduced, and the In two knife cutting courses, the pick-shaped cutter on placket hub is that the cut of next knife cuts out stress spron.Depth proposed by the present invention The heavily stressed coal petrography stairstepping cylinder of well is by the way of the cylinder of pre- cut sections one spron in advance on coal petrography, hence it is evident that subtract On little next knife end plate and helical blade, the cutting resistance of pick-shaped cutter, solves the mechanical mining of the heavily stressed coal petrography of deep-well Problem, improves the heavily stressed coal petrography cutting efficiency of deep-well in the case of fire-proof motor power is not greatly improved.The structure is using anti- Quick-fried Motor drive, meets downhole anti-explosion requirement, and coal mining machine roller is simple and compact for structure.
